When a stretch reflex excites one muscle it simultaneously inhibits the agonist muscles, which is called reciprocal inhibition this takes place due to reciprocal innervation.
Stretch reflex spatial threshold measure discriminates between spasticity and rigidity.
Ankle clonus was therefore hypothesized to be an exaggerated stretch reflex of the gastrocnemius and soleus only.
It is very risky, and is successfully used only by the most advanced of athletes and dancers that have managed to achieve a high level of control over their muscle stretch reflex (see section The Stretch Reflex).

The physiologic role of the stretch reflex is to help a muscle maintain a steady state.
Plyometric training involves high intensity, explosive eccentic-concentric muscle shortening that invokes the stretch reflex (stretching the muscle before it contracts to create a greater force) (6).
Spasticity is 'a motor disorder characterised by a velocity-dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex' (Lance 1980, p.
Anything less than six seconds, such as a ballistic stretch, does not incorporate the Golgi tendon organ, but, rather, the stretch reflex.
The benefit of using muscle energy techniques is that shortened muscles are lengthened by inhibiting the stretch reflex. The stretch reflex is the point at which resistance occurs.
